Abstract

Spotted Wing Drosophila (SWD), Drosophila suzukii is one of the most important pests in berry crops around the world. In this study, different models of traps were evaluated for monitoring adult SWD. The study was conducted in a commercial blackberry orchard of the cultivar Chester, in the municipality of Vacaria, RS, Brazil in May 2016. The treatments consisted of three trap designs, namely the European model (Hemitrap®), American model (plastic pot with 750 ml of capacity), and Brazilian model (red dyed, and colorless polyethylene terephthalate (PET) bottle of 250 ml of capacity). A total of 1,572 adults of SWD were captured, as 867 males and 705 females. The mean sexual ratio was of 0.56 ± 0.03 with no difference among trap models. The trap Hemitrap® showed the highest capture values for SWD adults as well as for other Drosophilidae. The American model did not show good results being surpassed by the PET bottle trap. When considering the number of entrapped insects per milliliter of attractant, per area of entrance, per evaporative surface, and per selectivity, the colorless PET trap (Brazilian model) is the most effective.
